Abstract

A geared air actuator comprising a piston 30 mounted for movement within a housing 3. The piston 30 has a front wall 31 and a hollow body portion 33 which extends rearwardly from the front wall 31. A spring 40 is mounted within the hollow body portion 33 of said piston 31. When pneumatic fluid is introduced into the housing 3 and against the front of the piston 30, it moves the piston 30 back against the action of the spring 40. When the introduction of pneumatic fluid is terminated the spring 40 will move the piston 30 back to its original position. The front wall 31 of the piston 30 is substantially thinner than the length of the body portion. <IMAGE>
